The university says the bridge - that once carried services like power lines and gas - it is beyond economic repair after a structural survey found it is unsound.

A heritage survey also found it is not suitable to be listed. A university spokesman said the removal of the bridge was considered the only option to prevent it deteriorating further and avoid the risk of collapse.

A previous application by Network Rail to demolish the bridge in March 2013 was approved by the City of Lincoln Council.
